Figure 72. — Operable model of a British locomotive, 1905. 



The original locomotive No. 146, a 4-4-4-T type with a 

 cowcatcher and outside cylinders, was built in 1905 by Beyer, 

 Peacock & Co., Ltd., of Manchester, England. The locomo- 

 tive and tender have a common frame. According to a small 

 plate affixed to the model, the original was the first locomo- 

 tive to be fitted with "Wardlaw's composite clackvalve." 

 This invention of the elder Wardlaw was installed at Buenos 

 Aires in January 1908, according to the legend on the plate.
